Python Pandas - 建立半開時間區間並檢查端點是否存在

要建立半開時間區間，請使用 **pandas.Interval()** 並將 closed 引數設定為 right。要檢查端點是否存在，請使用 in 屬性。

首先，匯入所需的庫：

import pandas as pd

使用值為“right”的“closed”引數設定半開區間。半開區間，即 (0, 5]，描述為 0 < x <= 5 (closed='right')

interval = pd.Interval(left=0, right=20, closed='right')

顯示區間

print("Interval...\n",interval)

檢查區間中是否存在元素。這表明 closed = right 只包含最右端的端點。

print("\nThe left-most element exists in the Interval? = \n",0 in interval)
print("\nThe right-most element exists in the Interval? = \n",20 in interval)

示例

以下是程式碼：

import pandas as pd

# Half-Closed interval set using the "closed" parameter with value "right"
# Half-Closed i.e. (0, 5] is described by 0 < x <= 5 (closed='right').
interval = pd.Interval(left=0, right=20, closed='right')

# display the interval
print("Interval...\n",interval)

# display the interval length
print("\nInterval length...\n",interval.length)

# check for the existence of an element in an Interval
# This shows that closed = right contain only the right-most endpoint
print("\nThe left-most element exists in the Interval? = \n",0 in interval)
print("\nThe right-most element exists in the Interval? = \n",20 in interval)

輸出

這將產生以下程式碼：

Interval...
(0, 20]

Interval length...
20
